How Garbage Collection Works

JavaScript automatically manages memory using garbage collection, freeing up memory occupied by unreachable objects.

• Garbage collection removes objects that are no longer referenced.
• JavaScript uses the mark-and-sweep algorithm to identify unused objects.
• Variables inside functions are cleared after execution unless referenced elsewhere.

function example() {
  let temp = { name: "Jake" }; // Object is created
  console.log(temp.name); // "Jake"
} // After this function runs, 'temp' is unreachable and garbage collected
